CVE-2011-4043
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedInteger overflow in an unspecified ActiveX control in SVUIGrd.ocx in ARC Informatique PcVue 6.0 through 10.0, FrontVue, and PlantVue allows remote attackers to execute arbitrary code via a large value for an integer parameter, leading to a buffer overflow.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed ARC Informatique productCheck Program Files for PcVue, FrontVue, or PlantVue folders, or look in Windows Registry under HKLM\SOFTWARE\ARC Informatique or HKLM\SOFTWARE\Wow6432Node\ARC Informatique for installed product and versionAffected if Product is PcVue between versions 6.0-10.0, FrontVue any version, or PlantVue any version
-
Locate SVUIGrd.ocx ActiveX controlSearch for SVUIGrd.ocx in the product installation directory (commonly in bin or system32 folders within the product path) and check Windows Registry under HKLM\SOFTWARE\Classes\SVUIGrd for the control registrationAffected if SVUIGrd.ocx file exists and is registered as an ActiveX control on the system
-
Verify ActiveX control is enabledCheck Internet Explorer settings (if applicable) or Windows COM component settings for SVUIGrd control, and review registry key HKLM\SOFTWARE\Microsoft\Code Store Database\Distribution Units for the ActiveX control kill bit statusAffected if ActiveX control is allowed to run (kill bit not set) and web browsers or applications can instantiate it
-
Confirm product version is within affected rangeReview the identified product version from step 1 against the affected ranges: PcVue >= 6.0 and <= 10.0, FrontVue all versions, PlantVue all versionsAffected if Installed product version matches the affected version ranges for any of the three products
Your environment is affected if you have PcVue 6.0-10.0, FrontVue, or PlantVue installed with SVUIGrd.ocx present and the ActiveX control enabled.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor patch or update to PcVue/FrontVue/PlantVue to remediate the integer overflow in SVUIGrd.ocx; consider disabling the ActiveX control if patch unavailable and network segmentation to reduce exposure.
